Until the first-corner accident which eliminated Marco Apicella at Monza in 1993, the unfortunate Argentinian had the unwanted tag of having just about the shortest Grand Prix career on record, for he was barely a third of a lap into his debut, the 1981 San Marino Grand Prix, when he was pushed off the track and into the wall, sustaining a broken ankle and wrist in the process.

He had three seasons in Formula 2 behind him: the first, in 1978, saw a few outings in a Chevron; the next, in a March, yielded his best finish (third place at Hockenheim); and he then endured a disappointing year with the troublesome Minardi.

Guerra recovered from his Imola crash to reappear briefly in Formula 2 at the end of the 1981 season in the Adriatic GP at Misano, finishing a distant 13th. However, his racing career was far from over, and on his return to Argentina Guerra was a front-runner in the Formula 2/3 CoDaSur series until 1987 when he made the switch to touring cars, in which he has been a regular competitor throughout the nineties.

Along with fellow ex-Grand Prix drivers Larrauri and Hoffmann, Miguel is currently one of the stars of the SudAm Super Touring championship.
